Distribution, phenotype and factors influencing the production potential of Nguni sheep.
(2018)The Nguni sheep of South Africa is an indigenous breed that is adapted to its environment. Migrating from Central Africa down the sweltering east coast of Africa down to Southern Africa, the sheep were exposed to different ... -
Effect of alternatives to antibiotic growth promoters on broiler performance.
(2006)No abstract available. -
The effect of crude protein and calcium intake on fertility of male broiler breeders.
(2016)Broiler parent stock are selected to ensure that good characteristics will be passed to the offspring but management of broiler breeder birds is different to that of broiler chickens. Feeding broiler breeders ad libitum ... -
The effect of crude protein intake on fertility in young and old male broiler breeders.
(2014)Due to genetic selection and improvements in broiler growth traits there have been negative influences on fertility in broiler breeder parents. This is mainly related to excess body weight gain resulting in the inability ... -
The effect of dietary protein and energy on feed intake and performance of laying hens.
(2005)This study was designed to devise a method by which the optimum combination of dietary energy and protein could be found that maximises the margin over feeding cost in an egg production enterprise. It was necessary to ... -
The effect of different methods of controlling urolithiasis on ovine mineral metabolism.
(1995)The widespread use of high-energy, low roughage diets among feedlot sheep has lead to the development of several production diseases (Bide et al., 1973). One of the least easily identifiable is urolithiasis, yet it is ... -
The effect of education on smallholder pig farmers' knowledge, practices and pig productivity in the Angónia District, Mozambique.
(2015)Smallholder pig production provides an important contribution for farmer livelihoods in many African developing countries. However, there are many constraints that limit pig performance and thus financial outcome. The ... -
The effect of feed type and diet quality on kinetics of digestion : the degradation properties of certain protein supplements, and the effect of concentrate supplementation and basal roughage quality on eating behaviour and particle passage from the rumen of sheep.
(2002)The unique anatomical structure of the ruminant animals' digestive tract allows them to convert forages containing high levels of fibre into the valuable products of meat, milk and wool. At the same time, an interdependent ... -
The effect of genotype, drying conditions and microbial enzyme supplementation of the nutritive value of hybrid and open pollinated maize grain for broiler feeding.
(2001)Three experiments were conducted to examine the effects of tannin inclusion in the diet; heat treatment of maize; and maize genotype and sex of broilers; on the nutritive value of maize-soyabean based diets, as affected ... -
The effect of group size and floor-space allowance on the efficiency of lysine utilisation by growing pigs.
(2005)Two experiments were conducted for this thesis, to determine whether an animal should be fed to its genetic potential in spite of this not being achievable due to an on-farm constraint. The first experiment was designed ... -
The effect of photoperiod after photostimulation on male broiler breeder fertility.
(2008)Fertility in male broiler breeders may be controlled through a number of different methods, including lighting programmes. Currently in the poultry industry, male and female broiler breeders are reared under the same ... -
The effect of photoperiod and feeding time on broiler breeder eggshell quality and oviposition time.
(2004)This study was conducted to determine the effect of photoperiod and feeding time on oviposition time and eggshell quality of broiler breeders. Five experiments were conducted in total. The effect of photoperiod on ... -
The effect of processing and supplementing millet stover with groundnut haulms and cereal brans on feed intake and growth performance of sheep.
(2010)Feeding of animal has become increasingly a big challenge for smallholder farmers in the dry season in most of Sahelian countries. Sheep has an important role in social and economical activity of smallholder farmers. ... -
Effect of roughage quality and period of day on rumen fill after meal termination, digestion, passage rates, and diurnal feeding behaviour in cattle fed on tropical roughage.
(2018)In tropical and subtropical regions, ruminant production is prominently dependent on tropical veld grass characterized by low nutritional quality. Feed intake is an essential constituent determining animal performance and ... -
Effect of roughage quality and period of meal termination on rumen fill.
(2015)This study was conducted to test the hypotheses that (1) reticulo-rumen fill remains the same with changes in nutritional quality of roughages and (2) irrespective of when meal termination occurs, reticulo-rumen fill in ... -
Effect of urea-ammoniation of dietary roughage and concentrate ratio on ruminal microbial activity in Jersey cows.
(2003)The effect of untreated roughages on digestibility and rumen fill of the gut was reviewed as physical mechanism influencing the regulation of roughage intake. The review of literature also focused on identifying factors ... -
Effects of diet quality and time lapse after meal termination on rumen load, rate of passage and feeding behaviour.
(2016)Ruminant utilisation of poor quality feeds is governed by rates of degradation and passage through the rumen. Firstly, the passage rate of feed material determines the degree of bypass nutrients and the efficiency of ... -
The effects of dietary crude protein on fertility of broiler breeder males.
(2010)Fertility of Broiler Breeders (BBs) has been researched over many years with inconclusive findings. Genetic selection and improvements in growth traits have had negative effects on fertility of BB. One explanation is ... -
Effects of dietary fibre on pig excreta characteristics and odours from slurry.
(2012)A study was conducted to test the effects that different high fibre sources and their varying inclusion levels had on the characteristics of the excreta (faeces, urine and the slurry), and on odour from the slurry of growing ... -
The effects of dietary lysine, crude protein, energy and feed allocation on broiler breeder hen performance.
(2013)This study was conducted to investigate the effects of varying levels of dietary lysine and feed allocation, on the performance of female broiler breeders. In trial 1, 900 Cobb breeders from 26 to 45 weeks of age were ...
